VPN Connection Over VPC

VPN Connection – IPsec

Internet Protocol Security is a protocol suite for securing IP (internet protocol) communications by authenticating and encrypting each IP packet of a communication session

IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session of negotiation of cryptographics keys to be used during the session

protection from DDOS

Static and Dynamic VPN Connections

static rquires all routes (IP prefixes) to be specified

dynamic VPN (BGP) supports max prefixes of 100

BGP over VPN supports 2-byte autonomous system numbers (ASN)

What is BGP (Border Gateway Protocol)

AWS VPN

Static VPN

Dynamic VPN

Path Selection Inside the VGW

iBGP and eBGP

VPN billing

data transfer charge

vpn cost per hour

Additional VPN Features

NAT Traversal (NAT-T)

Re-usable Customer Gateway

same customer gateway (CGW) IP

Create a new VGW and VPN then attach to your VPC

Only one VGW can be attached to a VPC at one time

Additional Encryption Options

phase 1 can now use Diffie-Hellman groups 2, 14-18, 22,23 and 24

phase 2 can now use Diffie-Hellman groups 1, 2, 5 14-18

Software VPNs on AWS

To Avoid being a single point of failure, AWS recommends HA architecture. To do this, host two software VPNs on Amazon EC2 instances in separate AZ and use a third Amazon EC2 instance to monitor the heath of the VPN connections.
